            Bug ID: 406574
           Summary: Can't load from *.xmi file (possibly error with
                    temporary file)
           Product: umbrello
           Version: 2.27.3 (KDE Applications 18.12.3)
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Severity: critical
          Priority: NOR
         Component: general
          Assignee: umbrello-devel at kde.org
          Reporter: vasniktel at gmail.com
  Target Milestone: ---

SUMMARY

I am unable to load my project via *.xmi file.

It says file does not exist (even though it does exist).

I've dig into sources and figured that it fails in UMLDoc::openDocument
function on line `if (!tmpfile.exists())` (513 line as of today). 

This is strange since the actual temporary file is being created (I've checked
it).

Hint:
Since previously everything worked fine I suspect `anaconda` might be the
reason for that (though this might sound awkward): during umbrello installation
it installed python 2 as well as a dependency; after I've installed anaconda,
it replaced my python 2 with python 3 without changing a command to execute it
(so now, if I type `python`, it executes python 3 instead of 2). If umbrello
does depend on python 2 it might cause some problems (it seems though I'm not
sure).
